FIELD OF THE INVENTION

The present invention relates generally to a skid mounted oil production processing system and method. More particularly, but not by way of limitation, embodiments of the present invention provide skid mounted oil production systems that include piping, instrument, electrical, and control components and connections, wherein the skid mounted production systems are capable of expansion or contraction as the requirements of the production well changes without the need to perform welding at the site.

BRIEF SUMMARY

The following presents a simplified summary of the disclosed subject matter in order to provide a basic understanding of some aspects of the subject matter disclosed herein. This summary is not an exhaustive overview of the technology disclosed herein. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is discussed later.

Oil production is the process by which a reservoir fluid is transported to the surface to be separated into oil, gas and water. If necessary, the obtained oil and gas will be treated and conditioned for sale or transport from the field to a petroleum refinery. The so called “upstream operations” consist of the exploration, development and production of crude oil, water and natural gas.

The production process is carried out in a surface installation. This installation includes wells, manifolds, pipelines, production lines, separators and other process equipment, as well as measuring equipment and storage tanks. Over time a well's oil production can decrease by fifty percent (50%), which results in equipment such as separators that were originally installed with the inception of the well, being oversized. However, replacing the equipment with smaller, less expensive in both initial and operating costs would require the production well to be shutdown and the system purged in order to perform the requisite welding and running of the various electrical, piping and pneumatic connections. In some cases the production capabilities of a well may have been underestimated and therefore results in the installed equipment being undersized. Embodiments of the present invention resolve these issues and allow for the contraction or expansion of oil production systems using skid mounted components, without the need for welding onsite.

Additionally, embodiments of the present invention drastically reduce both shop construction time and installation time. For example, construction time of traditional systems can take in excess of eight (8) weeks to complete, whereas construction of systems in accordance with an embodiment of the present invention can be complete on average of fourteen (14) days at a 30-35% reduction of cost and are completely ready for startup with full safety systems. Similarly, installation time of traditional systems oil production systems, can take four (4) weeks or more to complete. But in stark contrast, an entire system in accordance with an embodiment of the present invention, including skids and vessels can be installed and connected in approximately four (4) hours.

FIG. 1 depicts a crude oil and/or natural gas production system comprising a cluster of four (4) wells (not shown). As shown in FIG. 1, a production system according to an embodiment of the invention in which a multiphase fluid mixture comprising crude oil, water, natural gas and/or other fluids is produced by a cluster of four (4) wells (not shown) and transported via multiphase fluid transport pipelines to individual well high pressure bulk separators 10, 20, 30 and 40, and low pressure separator 50. As shown in FIG. 1, the equipment, including the piping, instrumentation, and pipe rack is mounted on several skid sections. The system also includes a fuel gas scrubber 60, tank battery 70 having ten (10) storage tanks 70 a-70 k, which store water, oil and other fluids and materials that are produced by the wells. FIG. 1 also shows the system including vapor recovery tower 80, flare knock-out drum 90 and flare stack 100.

FIG. 2 depicts a top view of the production system shown in FIG. 1. As shown in more detail in FIG. 2, the system includes a pipe rack 110 that is made of multiple sections 110 a, 110 b, 110 c, 110 d, 110 e, 110 f and 110 g of pipe, which are also mounted on skids. FIG. 3 shows an expanded view of a portion of the production system shown in FIGS. 1 and 2, wherein high pressure separators 10, 20, 30, 40, low pressure separator 50, fuel gas scrubber 60 and pipe rack sections 110 a, 110 b, 110 c, 110 d, and 110 e are shown. As also shown in FIG. 3, various instrumentation devices, including flow, level, pressure control and control valves are shown for the production equipment systems. FIG. 4 is a subset of the production system depicted in FIGS. 1-3, wherein high pressure separator 40, fuel gas scrubber 60, and pipe rack sections 110 d, 110 e are shown. As shown in FIG. 4, although pipe rack section 110 e is shown, low pressure separator 50 is not shown and only the piping connections are shown.

As discussed above, over time a well's oil production can decrease by fifty percent (50%), which results in equipment, such as separators that were originally installed with the inception of the well, now being oversized. However, replacing the equipment with smaller, less expensive in both initial and operating costs would require the production well to be shutdown and the system purged in order to perform the requisite welding and running of the various electrical, piping and pneumatic connections. In some cases the production capabilities of a well may have been underestimated and therefore results in the installed equipment being undersized. Embodiments of the present invention resolve these issues and allow for the contraction or expansion of oil production systems using skid mounted components, without the need for welding onsite.

FIGS. 5, 6A and 6B depict an embodiment of the invention for a three (3) well (well 1, well 2, and well 3) production system having well manifold 120 and high pressure separators 140, 150 and 160. No low pressure separator is depicted in FIG. 5. FIGS. 5, 6A and 6B also depict skid 130, which includes fuel gas scrubber 135, and pipe rack 200, which pipe rack 200 is made of multiple pipe rack skid sections. FIG. 5 also includes tank battery 170, vapor recovery tower 175, flare knock-out drum 180 and flare stack 190. FIGS. 6A and 6B also show heat exchanger 205 within pipe rack 200.

In an embodiment of the invention depicted in FIGS. 5-7, and as can be more readily seen in FIG. 6B, high pressure separator 160 is larger than high pressure separator 150, and high pressure separator 150 is larger than high pressure separator 140. As shown in FIG. 6A, only well 1 and well 2 have separators 140 and 160, wherein separator 140 is connected to well 1 and separator 160 is shown disconnected from well 2. Additionally, in accordance with an embodiment of the invention, the oil production modular system includes blinded piping and skid systems that can be used as additional wells are developed. For example, manifold 120 includes piping for well 1 and well 2, as well as additional piping 121 that can be used to commission a new well, e.g., well 3. Similarly, pipe rack 200 includes piping skid section 206 that can be used as additional wells are developed. Referring to FIG. 6A, during normal operation of this two well production system, well 1 provides production feed to separator 140, and well 2 provides production feed to larger separator 160.

In a further aspect of an embodiment, overtime, the production of well 2 begins to decrease, such that the large separator 160, that likely had been used since well 2's commissioning is now oversized. The operator can remove separator 160 from being associated with well 2, and a smaller separator 150 can replace larger separator 160 as shown in FIG. 6B. As also shown in FIG. 6B, rather than purchase a new separator for new well 3, well 3 is configured to provide production feed to larger separator 160, which had previously been used for well 2. In normal operation, well 1 provides production feed to separator 140, well 2 provides production feed to separator 150, and well 3 provides production feed to separator 160 as shown in FIGS. 5, 6B and 7.

As shown in FIGS. 5, 6A and 7, because the production capacity in well 2 had been diminished, embodiments of the present invention allowed the larger, more expensive separator 160 to be used with new well 3, and a smaller less expensive separator 150 to be used with existing well 2, without the need for welding. The replacement is quick and does not require that all of the production wells to be stopped and the systems purged due to the need for welding piping components.

An example of the removal and replacement of modular skid systems while the oil production processing system is in operation is now described. Referring to FIGS. 5, 6A, 6B and 12, open sand leg of separator 160 by opening block valves 305 and adjustable choke valve 306 causing sand to drain into sand leg discharge pipe 307. Block in well 2 at the well manifold 120. Drain separator 160 of oil and water fluids. In separator 160, close gas outlet, oil outlet, and water outlet by for example using block valves in pipe rack 200. Depressurize any residual gas pressure in separator 160. Remove flange nuts at separator 160 gas inlet. Remove flange nuts from separator 160 process gas outlet pipe flange at the pipe rack 200 junction. Remove flange nuts from separator 160 process oil outlet pipe flange at the pipe rack 200 junction. Remove flange nuts from separator 160 process water outlet pipe flange at the pipe rack 200 junction. Disconnect tubing connections 230 (see FIG. 10) of pneumatic manifold at separator 160 pipe rack 200 junction. Disconnect electrical connections 240 (see FIG. 10) at junction between separator skid 160 and pipe rack 200. Remove separator 160 from pipe rack 200 by pulling separator 160 away from pipe rack 200 to disengage knife 220 and fork 210. Using a crane or other suitable mechanism, lift separator 160 skid with, e.g., lifting eyes, and reposition separator 160 out of the way.

To replace the larger separator 160 with smaller separator 150, after larger separator 160 has been removed, place smaller separator 150 in close proximity to pipe rack 200 skid. Using the alignment guide plates of fork 210, pin 215, and knife 220, push separator 150 into position at pipe rack 200 skid until knife 220 and fork 210 alignment plates and pin 215 engagement occurs. Connect tubing connections 230 (see FIG. 10) of pneumatic manifold at separator 150 pipe rack 200 junction. Connect electrical connections 240 (see FIG. 10) at junction between separator skid 150 and pipe rack 200. Install ⅛″ gaskets between flange pairs for well head inlet, and gas, oil, and water outlets. Install studs and nuts, torque to specification. Follow pressurization and start-up procedure per facility. As shown, replacing oversized and larger separator 160 with the smaller separator 150 did not require any welding, that would require the entire production well site to be shut down and the system purged in order to perform the requisite welding and running of the various electrical, piping and pneumatic connections.

In another embodiment of the present invention, additional parts are or the entire production system is constructed on skid section systems as disclosed herein, wherein component pieces of the system, including pipe racks 110 a-110 g, 200, vapor recovery tower 175, flare knock-out drum 180, flare stack 190, fuel gas scrubber 60, and a multi-well separator are constructed and designed to be replaced in a modular form. The modular construction and replacement of additional equipment in accordance with an embodiment of an invention include, high-pressure test separators, low-pressure test separators, line heaters, heater treaters, gas dehydration units, gas powered units, combustors, slug catchers, bulk separators, sand separators, methanol injection skids, pig launchers and receivers, safety systems, instrumentation and electrical equipment skids, SCADA systems, flares, and other equipment that may be used at a well head production system.

Cold Weather Packaging Modular Production System

FIG. 16 illustrates a further aspect of the modular production system embodiment, wherein a cold weather packaging modular production system is provided. In these systems, the piping is heat traced and insulated in a complete package prior to delivery, including the pipe rack piping sections and equipment skid piping. The heat trace on the piping can include connectors or terminators for connecting the ends of the heat tracing across the pipe rack and equipment skids during installation. The equipment, such as separator skids 510, 520 can also be outfitted for cold weather operation, including insulated vessels and heated steel box frames 515, 520 that cover the instrumentation and controls to shield equipment from cold winds to avoid freezing of condensed liquids in the tubing control lines and control valves. Further, the separator can be a heated type that includes a fire-tube to promote gas-liquid separation in cold environments.

Knife and Fork Alignment Pin

As more fully depicted in FIGS. 6A, and 6B through 11, the skid systems include knife 220 and fork 210 pin connectors connected to the rigid beam structures that are used to align and connect the skids. For example, the skid systems depicted in the figures can be mounted on steel I-beams. Referring to FIGS. 8-10, and 14-15, the knife 220 and fork 210 pin connectors are alignment guide plates with a self-setting elevation pin 215 slot. Each fork 210 includes two guide plates that are welded at one end to the beam web. The other end of the fork 210 guide plates include angled projection portions. The angled projections of fork 210 help guide the skids into alignment as they are pushed together. A side sectional view of one guide plate of fork 210 is shown in FIG. 14A. As shown in FIG. 14A, the guide plate is welded at one end to beam web, and the other end includes an outwardly angled portion. As shown in FIG. 14, the fork 210 includes pin 215 that can be a small length of round stock bar that can have a length slightly greater than the skid beam web thickness. The pin 215 is welded between the fork 210 two guide plates to keep the free end of the fork 210 guide plates separated. Pin 215 serves as the self-leveling pin as the fork 210 engages the knife 220 while riding in the pin slot. As shown in FIG. 15, the knife 220 slot can be an elongated rounded cutout that is engaged with the fork 210.

Additionally, other designs of the fork connector can include the guide plates being welded to a beam web without the intervening pin spacer that is welded to both side plates. Here the two skid sections are secured together by the open space between the guide plates engaging the web of the opposing skid section beam. Additionally, an embodiment of the invention includes a single guide plate, such as that shown in FIG. 14A. In this embodiment, as more fully shown in FIGS. 21A, 21B, and 21C, the guide projection 221 is a single plate that is welded to the web of the beam, and includes an outwardly angled end, so that the angled side connects with the web of the opposing beam and guides the skids into alignment as they are pushed together. As the skid sections are pushed together, the guide projection 221 bumps the web of the opposing skid section into proper alignment. As shown in FIGS. 21B and 21C, when the skids are pushed together using the alignment guide 221, it leaves companion flange faces from opposing skids ready to bolt up with minimal final adjustment of pipe headers and ready for a gasket insert.

As shown in FIG. 11, an embodiment of the present invention is designed such that as the skids are pushed together and aligned using the alignment knives 220, forks 210 and pins 215, the interconnecting flanges 250 are pushed up leaving a ⅛ inch gap in order to slide in the necessary gasket. In a further embodiment of the present invention as shown in FIG. 11, the system the skid systems include conductors carrying electrical signals for power, signal, measurement or control in a quick connect type system that are connectable to conductors in other skid systems of the production system by the connection of conductor carrying conduits or emt tubing 240 within the systems, or terminating connectors on the skid systems, which removes the need to run wire and conduit during the installation at the production well site. In a further aspect, cable trays are provided on the system to install “pre-run” electrical cable that is combined with skid-edge mounted junction boxes populated with terminal blocks.

In a further embodiment, as shown in FIG. 11, the skid systems also include tubing 230 jumpers for pneumatic connections between the skid systems, which removes the need to run tubing during the installation of a skid system at the production well site. As shown in FIG. 7, skid 150 a represents a portion of the skid that high pressure separator 150 as seen in FIG. 6A is mounted on. Referring back to FIG. 7, skid 140 a similarly shows a portion of the skid base that high pressure separator 140 is mounted on, and skid portion 130 a represents a portion of skid 130 wherein fuel gas scrubber 135 is mounted. As is further illustrated well manifold 120 is shown pulled back before hook up with the mating flanges on pipe rack 200 and hook up of the knife 220 and fork 210, such that when the knife 220 and fork 210 (also depicted in FIG. 9) are connected as similarly depicted between skid portion 130 the flanges on well manifold 120 are mated to the flanges on pipe rack 200 for bolting the flanges one to the other. Still a further aspect of an embodiment of the present invention can include the use of testing components such as testing separators for use with single or multiple wells. FIG. 8 is an enlarged view of FIGS. 5-7 showing skid portion 130 and the piping and alignment pin connections.

Integrated Separator System

FIGS. 12A, 12B, and 13 illustrate an aspect of an embodiment, depicting an integrated sand separator system 300 in one or more of the high pressure separators 10, 20, 30, 40, 140, 150 and 160. In this embodiment, the high pressure separator 10 is connected to the wellhead and includes an internal sand separator system 300 disposed within the high pressure separator 10. The sand separator system 300 filters out the majority of the sand from the well head fluid stream. The sand separator system 300 includes a sand weir plate 301 that is located before an oil weir 302. The sand weir plate 301 is lower that the oil weir 302 in order to collect the sand and keep it from reaching the water out nozzle 303. During operation, sand enters the high pressure separator 10 with the incoming well head fluid inlet 315 and impinges upon an inlet diverter 310 mounted inside the separator vessel 10. When the sand granules impact the inlet diverter 310, a change in momentum of the sand granules is created; causing the sand granules to separate from the fluid and fall to the bottom of the high pressure separator 10 where they are collected at the base of the sand weir plate 301.

Sand system 300 can further include a drain system that includes sand out nozzle 304, double block valves 305, adjustable choke valve 306, and sand leg discharge pipe 307. As shown in FIGS. 12 and 13, the sand leg discharge pipe 307 is routed around the water drain piping 308. The sand leg discharge pipe 307 ties back into the water out header downstream of instruments (for example a vortex flow meter that can be inserted in spool 311) and liquid control valve 312 to avoid the sand's interference with or damaging the instrumentation. The sand system 300 can also include a self-cleaning feature, wherein after the separated sand granules are collected at the base of the sand weir plate 301, the sand is drained from the high pressure separator 10 using a sand choke valve 306, eliminating the need to shut down the system to vacuum remove the sand.

In yet another aspect of an embodiment of the present invention, a level measuring device 313, such as an ultrasonic/sonar level device, a radar level device, an ultrasonic level device, or a capacitance level device measures the level of collected sand and communicates this level to the control or monitoring system (not shown). A further aspect of an embodiment can include choke valve 306 having an actuator or a separate actuator controlled control valve, wherein the control system actuates choke valve 306 or control valve to drain the sand from the high pressure separator 10. The control system can also be programmed to send a signal to open the actuated choke valve 306 or control valve based on when the sand level, as measured by level device 313, reaches a desired setpoint.

Stacking Posts

FIGS. 17-19 illustrate a further aspect of another embodiment, depicting a stacking system for shipment of multiple pipe racks and other equipment skids (see FIG. 19) that results in reducing the number of trucks needed to transport production system components. As shown in FIGS. 17-19, four pipe racks 405, 410, 415 and 420 are stacked for transport and delivery. Stacking posts 401 have top 402 and bottom 403 plates with bolt holes. The stacking posts 401 are bolted to the pipe rack steel beams 406, 411, 416, and 421 at multiple places along the pipe rack in order to distribute the load. As can be seen in FIG. 19, the stacking posts 41 can be sized as needed to accommodate the multiple pipe racks. By using the stacking system embodiment, multiple pipe racks can be shipped on one truck load, as opposed to four, reducing the cost of shipping and speeding up the time of delivery and setup of the modular production system.

Data Analytics and Neural Networks

In a further aspect of an embodiment, the system includes a control system, such as a DCS, PLC, SCADA, or wireless control system (e.g., wireless instrumentation and control devices that communicate over a wireless network), or a combination of these types of control systems that are operatively in communication with the modular production system's instrumentation, actuators and valves. The control system can be used to monitor and control the operation of the production system. Additionally, the system can be controlled and monitored remotely, and production system data for one or a multitude of production systems is collected, analyzed, and used for benchmarking purposes, as well as optimization and predicting operation of production systems, including separators, to generate and predict production systems operational setpoints, maintenance needs, measurements, and values, including service to the equipment, such as the need to drain sand from the integrated sand separator. Additionally, the need to replace an oversized, or in some cases undersized separator, can also be determined using these systems. For example, and as shown in FIG. 20 and as discussed further below, there is data collection via a computer communication network of production system operating parameters and determined setpoint data for a production system, including the separator systems, wherein using data analytics, artificial intelligence, machine learning and/or neural network methodologies to: predict the subject, a related, or an unrelated production system's performance and/or operational setpoints; generate benchmarking metrics for production systems' operation and maintenance; and/or generate setpoints and anticipated measurement and production system operational values.

FIG. 20 shows an example of a deep neural network (NN) architecture 600 including a matrix of connected neuron processors. The matrix of neural processors is configured as a computation unit that operates as a two-dimensional systolic array. The two-dimensional systolic array includes multiple cells that are configured to identify probabilities for three categories of content. By way of example, the input neurons x1 through x3 are activated through input data and operate as sensors that perceive the input, and are for example in an embodiment of the invention, well production data, such as measurement data that is received from well and separator instrumentation, and can include inlet well fluid flow rate, outlet fluid, including gas flow, oil flow, water flow, system pressures, sand level, water level, and oil level, physical and chemical characteristics of the crude, operating pressure, operating temperature, and rate of throughput, including rate of increase or rate of change of these parameters. Production system can include instrumentation that can measure these parameters, and data from these parameters can be collected using a wireless network in communication with the instruments, and control or monitoring systems.

The middle layers, sometimes referred to as the hidden layers, which include neural processor layers h11 through h14 and h21 through h24, are activated through weighted connections and receive activation data from previous neural processors. For the sake of simplicity, two middle layers are shown although these layers can be multiples of what is shown and the number of layers depends upon the input and how “deep” of an accumulative learning process is required to obtain a reliable result. Some of the neural processors in the middle layers will influence the output by triggering events based upon one or more other events occurring in the middle layer or directly from input data. Depending upon the accuracy and comprehensiveness of the input data, the problem to be solved and how the neural processors are connected, obtaining an output z1 and z2, in order to, for example, predict timing of the need to drain the sand from the high pressure separator. As shown in FIG. 20 the deep neural network 600 is configured to analyze each of the vectors to generate probabilities to determine a final confidence score for the output z1 and z2 that reliable within a degree certain.
